| 15 This module provides support for building a new version of the |
| 16 Python executable. This will be necessary on systems that do |
| 17 not support shared libraries and may be necessary with C++ |
| 18 extensions. This file contains everything you need to build |
| 19 a new version of Python from include files and libraries normally |
| 20 installed with the Python language. |
| 21 |
| 22 This module will automatically grab all of the Python modules |
| 23 present in your current Python executable (including any special |
| 24 purpose modules you have enabled such as Tkinter). Thus, you |
| 25 may need to provide additional link libraries when compiling. |
| 26 |
| 27 This library file only works with Python 1.5. A version |
| 28 compatible with Python 1.4 is available as embed14.i and |
| 29 a Python1.3 version is available as embed13.i. As far as |
| 30 I know, this module is C++ safe. |
